Yup ...ive made my mind ,if this game doesn't get released in the next 10minutes I'm going to shoot myself .....
But you could put braces on the bank and stone to stop erosion, just dirt would get removed fast, but let's wait for the dev to say something.
I agree I would hate it if I had been mining and found something cool and then it gets eroded away when I'm not even there . I think it's a great idea but I don't think people would want to spend time erosion proofing there house when they could be searching through dungeons and having an amazing time -maybe it could be something you could turn on or off?
An option would be cool, but if there is lots of rivers that would be a lot of data for the iPhone to calculate.
